Polietersülfon (PES) Membran Sentezinde Koagülasyon Ortamının Etkileri
Polimerik membranlar iyi film oluşturma, esneklik, dayanıklılık, ayırma özellikleri ve düşük maliyet gibi avantajları nedeni ile membran ayırma proseslerinde yaygın olarak kullanılmaktadır. Membran sentezi sırasında kullanılan koagülasyon ortamının değiştirilmesi ile membranların gözeneklilikleri arttırılabilir. Gözenekliliği artan membranlar daha yüksek akıda filtrasyon gerçekleştirerek arıtma maliyetini düşürür. Bu çalışmada polietersülfon membranların sentezi sırasında koagülasyon ortamına farklı konsantrasyonlarda tuzlar eklenerek membran gözenekliliği üzerine etkileri araştırılmıştır. Elde edilen sonuçlara göre koagülasyon ortamında %5 NaCl çözeltisi eklenmesi membran gözenek boyutunun küçülmesine neden olmaktadır.
Effects of the Coagulation Medium on the Polyethersulphone (Pes) Membrane Synthesis
Polymeric membranes are widely used in the separation processes due to their good film forming ability, flexibility, durability, separation properties and low cost. Membrane porosity can be changed by changing the composition of the coagulation bath used during the synthesis. Membranes with high porosity reduce the filtration cost due to the increased flux. In this study, polyethersulphone membranes were synthesized in a coagulation medium of different salts at different concentrations in order to investigate the porosity effects of the coagulation mediums. Based on the results, membrane pore size can be reduced by using %5 NaCl solution as a coagulation medium during membrane synthesis.
